The mission quarterback Johnny Manziel outlined in a statement earlier this month is to regain the trust and respect of the Browns and their fans after he spent more than 10 weeks this offseason in an inpatient rehabilitation facility that specializes in alcohol and drug addiction treatment.



Well, apparently All-Pro left tackle Joe Thomas has been impressed with the dedication Manziel has shown thus far during his comeback attempt. Manziel has been participating in the Browns' voluntary offseason workout program since it began April 20.



"Last year on a Saturday, you might see a picture of him on Instagram floating in a swan drinking champagne," Thomas told NFL Network on Tuesday. "This year on a Saturday if you came in the building, you'd see him studying his playbook and watching film with his coach. It's pretty apparent he's realized how important football is to him, and he's realized that in the NFL you can't get away with maybe some of the things that you did in college because it's a big boys' game now."



Earlier this month, Thomas told ESPNCleveland.com Manziel "lost probably a lot of trust among the guys on the team last year by the way he handled himself once he became the starter" in December. A week later, Thomas told a group of beat writers "there was some doubt based on what [Manziel] did last year if football was the most important thing."



For example, Manziel admitted to partying too late with friends the night of Dec. 26 while he was on injured reserve and failing to report to team headquarters on time the next morning to receive treatment on his hamstring. The team reportedly sent security personnel to rouse Manziel at his downtown Cleveland apartment because it couldn't reach him by phone. The Browns fined Manziel, the 22nd overall pick in last year's draft.



"Towards the end of the season, even when he wasn't there, obviously, missing meetings and practice and things like that, it's just little things, and when you're a quarterback it's the little things that are the most important," Thomas said in the interview with NFL Network. "I think those were the things that were apparent by the end of the year, and I think he saw them in himself based on the things that he said right after the season and the steps and the actions that he took in January, February and March. To see the guy in the building right now is night and day from where he was last year in his commitment, and I think he has a bright future ahead of him."
